Generally speaking, ginseng is one of the most potent ‘Cure-Alls’ we know of today, with an amazing capacity to improve our health.
But how much does it improve brain function? Is Ginseng a nootropic, or just a useful herb?
This article also looks at the differences between Asian Ginseng and American Ginseng.
You may prefer one over the other, depending on the benefits you’re looking for; the active ingredients in each vary.
Asian ginseng, AKA Panax Ginseng, is known to be ‘hot’ or stimulating.
American ginseng, or Panax Quinquefolius, has more of a ‘cooling’ effect.
So without further ado, let’s find out about Ginseng as a natural neutraceutical, shall we?
What is Ginseng? – Background
Ginseng has been used as a medicinal herb for thousands of years.
Most people assume that it originated in Asia, but Native North Americans have been using it for hundreds of years as well.
There are 13 species of Ginseng that we know of, but Panax Ginseng and Panax Quinquefolius are the 2 species most commonly used for their healing properties.
Ginseng is usually cultivated in China, Korea, Japan, America, and Canada. The density of active ingredients is increased when it is grown in colder climates, and as the plant gets older.
Not surprisingly, Canada is the largest exporter of Ginseng in the world, and the plants are only harvested after growing them for at least 5 years.
The main active ingredients in Ginseng are called ‘Ginsenosides’, and there are hundreds of them.
About 200 ginsenosides have been identified in Panax Ginseng, and about 100 have been isolated from Panax Quinquefolius.
In total, about 50 of these compounds have been found in both Asian Ginseng and American Ginseng, while the other compounds vary with the plant variety.
This is why Asian Ginseng and American Ginseng can each be better at providing certain benefits, which we will discuss more later.
Ginseng Benefits – How Helpful is it?
Panax means, “Cure-All” in Greek, and Ginseng has indeed been found to help with just about everything.
This is a laundry list of some of the issues Ginseng is good for:
- Heart Disease
- Neurodegenerative Diseases
- Auto-Immune Disorders
- ADHD Symptoms
- Erectile Disfunction
- Fatigue – Mental & Physical
- Digestive Issues
- Skin Problems
- Poor Circulation
And it’s even good for the cold or flu! Whew! That’s quite a list.
You’re not the only one. I have a Ginseng supplement I keep handy for those days when I am feeling overwhelmed, or think I need an energy boost.
It’s really good for fighting off fatigue, and you don’t crash later once the effects wear off.
But the question still remains; how can one herbal medicine do all of these things? Is it really that effective?
What does Ginseng do for the Body?
Ginseng is an Adaptogen. What this means is that it allows the body to maintain it’s internal balance, even under stress.
I would first like to go over some of the more general health enhancements Ginseng has to offer, and then look at the nootropic benefits later.
The advantages Ginseng offers as an adaptogen are as follows:
- Stress Protection
- Immune Booster
- Fatigue Prevention
Ginseng has several compounds in it other than ginsenosides that account for all of these benefits.
It would be far beyond the scope of this article to discuss them all, so I’ll just mention a few of the better known constituents.
Ginsenosides – are steroid-like in nature, and we know that they act as antioxidants.
The antioxidant activity soaks up free radicals, thereby preventing them from causing tissue damage at the molecular level.
This in turn prevents inflammation, which ultimately translates to protection from all kinds of diseases.
Ginseng also regulates stress responses.
There are 2 ways that Ginseng manages to accomplish this:
- Increasing the effectiveness of GABA
- Equalizing Cortisol Levels
GABA, or Gamma Aminobutyric Acid, is is an inhibitory neurotransmitter best known for its’ ability to block the release of other neurotransmitters.
GABA causes a general slowing down of the nervous system, with a very noticeable calming effect.
Studies have shown that ginsenosides enhance the efficiency of GABA. They accomplish this by increasing the sensitivity of GABA receptors in the brain.
At the same time, ginsenosides also put an upper limit on how much Cortisol is released into the bloodstream.
Cortisol is a stress hormone, and when Cortisol levels get too high for too long, all kinds of health problems can result.
What this means is that during times of stress, taking Ginseng has a modulating effect. It prevents extreme fight-or-flight responses that can create imbalances in brain chemistry, and the adrenal system.
Ginsan – a polysaccharide that normalizes immune responses.
Ginseng supplementation increases levels of Ginsan in the body. Ginsan encourages the growth of dendrite cells, which in turn produce cytokines. Cytokines are proteins that signal an immune response.
At first glance, you might think that the presence of extra Ginseng would simply give the immune system a boost.
However, Ginseng also promotes the production of Nitric Oxide gas (NO) in the dendrite cells.
Additional NO in the bloodstream actually lowers cytokine levels slightly to keep them in check.
The end result is that the immune system is strengthened, but immune responses are slightly suppressed at the same time, thereby preventing any issues with inflammation.
Last but not least, keeping Cortisol levels and immune reactions in check helps prevent injury to mitochondria.
This keeps energy metabolism at an optimum level.
So to sum it all up, Ginseng prevents disease by reducing oxidation, inflammation, and the negative effects of stress.
It also improves the efficiency of the immune system, and helps fend off fatigue.
These benefits are somewhat general in nature, but now it’s time to get more specific.
Let’s look at how Ginseng works as a nootropic, shall we?
Is Ginseng Good for the Brain? – How does it Improve Cognition?
Ginseng enhances the activity of the brain in a number of ways.
The main mechanism is stopping the breakdown of neurotransmitters so that they continue to do their work.
The end result is sustained levels of activity in the areas of focus and memory, as well as improvements in mood and working capacity.
Ginseng boosts brain function by acting as a:
- Neurotransmitter Optimizer
- Memory Enhancer
- Neural Growth Factor
I mentioned earlier that Ginseng increases the amount of Nitric Oxide gas (NO), in the bloodstream.
One of the added bonuses of that effect is that Nitric Oxice acts as a vasodilator, increasing blood circulation.
When more nutrients and oxygen can be delivered to the body and brain, energy levels improve.
Studies have also shown that Ginseng can be good for depression. The 3 neurotransmitters associated with depression are Dopamine, Norepinephrine, and Seratonin.
Ginseng prevents these neurotransmitters from being broken down, acting as a reuptake inhibitor.
When concentrations of these neurotransmitters are sustained, it can help with depression. (This can vary depending on the root cause of the persons’ depression)
Typically, ADHD symptoms are tied to low levels of Norepinephrine and Seratonin. Maintaining high levels of these neurotransmitters can help reduce their severity.
A clinical study on children with ADHD in Korea found that using an extract of Panax Ginseng increased learning ability, memory, auditory reaction time, and attention.
It goes without saying that higher levels of Dopamine, Norepinephrine, and Seratonin will result in better memory and cognition.
However, some studies also suggest that ginsenosides can encourage increased production of Nerve Growth Factor (NGF) as well.
NGF facilitates the growth of new brain cells and nerve fibers. This is a good indicator that Ginseng improves overall brain health.
Now let’s give some thought to how Asian Ginseng and American Ginseng can offer different advantages as nootropic supplements.
Asian Ginseng vs American Ginseng – Characteristics
The first thing people notice when comparing Panax Ginseng and Panax Quinquefolius is how they affect body temperature.
Generally speaking, Asian Ginseng is considered “hot”, and is often prescribed for poor circulation.
American Ginseng, by comparison, has been shown to cool overall body temperature when sleeping.
Asian Ginseng is understood to be stimulating, and has been found to improve memory, and decrease recovery time from intense cognitive tasks.
One study also found Panax Ginseng to be especially good at treating depression. In fact, the researchers found it to be nearly as effective as the prescription medication fluoxetine.
Asian Ginseng has also been tested for its’ ability to increase physical endurance. However, as of this writing, the results so far have been inconclusive.
An extensive study on American Ginseng noted a few areas where Panax Quinquefolius performed better than Panax Ginseng. These are the characteristics that set it apart:
- Increases Acetylcholine Levels
- Stronger Anxiolytic
- Better Antioxidant for Lipids
- Chelates Heavy Metals
American Ginseng was found to encourage more production of the neurotransmitter Acetylcholine.
They also discovered that American Ginseng has a more pronounced ability to increase the sensitivity of GABA receptors in the brain.
This results in a better ability to maximize stress resistance, and provide more of a calming effect, making it a good prescription for hyperactivity disorders like ADHD.
American Ginseng is also more effective at preventing the oxidation of fats, and has the capacity to clean heavy metals out of the body.
Overall, I think that if I wanted a Ginseng supplement that gave me more motivation and drive, I would use Panax Ginseng.
And if I needed something with more of a calming effect, American Ginseng would be my first choice.
So now that we have gone over the unique advantages of Asian & American Ginseng, let’s take a look at how to use them as supplements.
Ginseng Dosage – Recommendations for Best Results
Ginseng is available as a dried root, extracts, powder, tablets, and capsules. There is a big difference between using an extract and the root itself. Extracts are concentrated, so you won’t need as much.
Some people prefer using a product that is in it’s original form, thinking that it hasn’t been tampered with as much, and is more pure.
I recommend looking for a supplement that is ‘Certified Organic’, and is ‘GMP Certified’.
GMP stands for ‘Good Manufacturing Practices’, and it means that the manufacturer is following guidelines set out by the FDA.
The products are also tested by a neutral 3rd party for safety, effectiveness, and purity before distribution. It’s the golden standard for quality in the supplement industry.
You should also keep in mind that the production standards overseas are not as stringent. If you are looking at getting a good Panax Ginseng supplement, be cautious.
There are some neurohackers that swear by American Ginseng simply because it’s so much easier to find a high quality product that’s safe and effective.
If you are using capsules or tablets, the recommended dosage is usually 100-400 mg/day.
However, the potency of the supplement can vary quite a bit, depending on the ginsenoside content, and how the Ginseng was prepared.
You really just need to follow the directions on the label from the manufacturer.
Ginseng also needs to by cycled. Remember, ginsenosides are steroid-like in nature.
It’s generally not a good idea to take Ginseng for extended periods of time without taking a break.
2 options for cycling include taking your Ginseng Monday to Friday with the weekends off, or taking it for 3 weeks, and taking the 4th week off at the end of the month.
Ginseng Side Effects – What You Need to Know
Side effects are generally pretty mild, but can include upset stomach, dizziness, and insomnia.
These are some of the folks that should refrain from taking Ginseng, or at least consult with their doctor first:
- Anyone under 18 years old
- Ladies that are Pregnant
- Ladies that are Breastfeeding
- Anyone on Blood Thinners
- Anyone taking Anti-Depressants
- Anyone taking Anti-Psychotic Drugs
Ginseng can affect hormone balance, thin the blood, and lower blood sugar. It also regulates neurotransmitter levels, so it can double up the effects of anti-depressants, and severely interfere with anti-psychotic drugs.
You should also watch your alcohol and caffeine intake while you are using Ginseng.
However, you should still consult with your doctor first before supplementing with either variety of Ginseng if you are diabetic. Just in case.
It could make your blood sugar drop too low.
Keep in mind, however, that Ginseng is generally considered quite safe for most individuals. It has been used for thousands of years, and has a lot to offer.
In fact, if you are interested in trying Ginseng, but are a little bit worried about how to find a good supplement, I have a few recommendations for you.
Best Panax Ginseng Supplement – A Good Value
The first is for a Panax Ginseng Supplement from Double Wood. Double Wood provides decent supplements at a reasonable price, and their products are safe.
Double Wood is GMP Certified, but they do not provide organic products. The name of the game with them is value.
If you are looking for a Ginseng supplement that is more stimulating, can improve blood circulation, and perhaps provide a bit of motivation, I recommend you give this product a go.
Best Ginseng Supplement – for American Ginseng
The second recommendation is for an American Ginseng product from a company called Brain Forza.
The supplements from Brain Forza are very clean, Certified Organic, and are rigorously tested for effectiveness.
Brain Forza American Ginseng is my supplement of choice for extra energy, and I keep some handy all the time.
I find that American Ginseng works better for me because I like the calming effect that it provides. Sometimes I get frazzled at work, and this Ginseng supplement is just what I need.
The cooling effect of American Ginseng is also great for me because I’m a hot sleeper.
Sometimes I wake up in the middle of the night, and I’m just sweating like crazy! It’s not hot in the room. It’s just me.
But I digress.
Finally, Brain Forza specializes in providing high quality organics; mushrooms and herbals in particular.
I really like their products, and feel safe using them. This supplement is the best Ginseng product I’ve ever tried, and I’ve sampled quite a few.
So if you are thinking of trying an American Ginseng supplement, give it a go. I think you’ll be very impressed.
In any case, let’s wrap things up, shall we?
What’s Ginseng Good for? – What’s the Best Type for You?
Ginseng is especially useful for combating chronic fatigue.
The main advantage it has over stimulants is that it provides clean energy; there’s no crash when the effects wear off.
It also provides stress protection, a boost to your immune system, and enhances your mental capacities all at once.
So is Ginseng a nootropic? Does it boost our brain power enough to be considered a brain booster?
Yes, I think it does. We have to be mindful of our caffeine and alcohol intake, and a few contraindications, but ginseng is generally quite safe.
Ginseng is the ‘Cure-All’ herbal nootropic you always want to have in your medicine cabinet. Just in case.
In answer to the debate around Asian Ginseng vs American Ginseng, I think it really depends on what you need, and your personal preferences.
If you feel like you need something stimulating, or ‘Yang’, as they say in Chinese medicine; go for Panax Ginseng.
If you need more of a calming effect, or something that is more ‘Yin’, American Ginseng is your best bet.
One thing is for sure, whichever variety of Ginseng you choose, it will strengthen your constitution and protect you from all kinds of ailments.
Even the common cold.
